description

These monolithic, positive-edge-triggered flipflops

utilize TTL circuitry to implement D-type

flip-flop logic with a direct clear input.

Information at the D inputs meeting the setup time

requirements is transferred to the Q outputs on the

positive-going edge of the clock pulse. Clock

triggering occurs at a particular voltage level and

is not directly related to the transition time of the

positive-going pulse. When the clock input is at

either the high or low level, the D input signal has

no effect ar the output.

These flip-flops are guaranteed to respond to

clock frequencies ranging form 0 to 30 megahertz

while maximum clock frequency is typically 40

megahertz. Typical power dissipation is 39

milliwatts per flip-flop for the 4273 and 10 milliwatts

for the 4LS273.
